Alex Manninger 5

Beaten at his near post for the second goal, and could get nowhere near the third. Barring an injury crisis, Reds fans won’t see a lot more of him this season.

Trent Alexander-Arnold 6

Comfortable on the ball, but some work to do off it. Will need to improve physically before he becomes a regular.

Andre Wisdom 5

Harshly penalised for the penalty, but struggled at centre-back alongside Matip.

Joel Matip 5

A little rusty on his return from injury, which can be expected. Beaten for strength by Jhon Cordoba for Mainz’s second, which may be a concern to Klopp. May have to sit out at the Emirates.

Alberto Moreno 6

What was it Jamie Carragher said about left-backs? Well Liverpool still need one. Erratic as ever, Moreno was everywhere here. Not always in a good way.

Emre Can 6

Saw a lot of the ball in the first period but struggled to make a real impact.

Jordan Henderson 6

Will be fearing for his place in the side. The skipper played 73 minutes and while nobody can question his desire, Henderson struggled to really stamp his authority on the game.

Marko Grujic 7

Showed flashes of his quality - setting up Divock Origi for Liverpool’s only chance of the first half before immediately departing the pitch with an ankle injury. Jurgen Klopp will hope it’s not serious.

Adam Lallana 6

Superb against Barcelona, but on the periphery here. Understandable too, given the work the 26-year-old put in against the Catalan giants.

Ben Woodburn 6

Showed some neat touches and won the Reds a corner with a nice piece of skill on the touchline. Otherwise quiet.

Divock Origi 6

Cut a frustrated - and isolated - figure up front. He wasn’t afforded the space he was at Wembley, and he struggled with his back to goal.
